Lefty 6mm BR repeater advice

Well I decided I needed a high volume LR rifle I can shoot a lot or rounds through without the barrel getting hot too fast. I want something easy and cheap to load with great brass. I'm thinking the 6mm BR should work quite nicely. I really want it to be a LH repeater. I could rebarrel my rem700 22-250 but it's still shooting well even though the round count is getting up there. So I was thinking about a Predator action. It seems Wyatt's makes a BR box that would feed the rounds. Is this a good way to go with either action? Is there another action or way to go about building a LH repeater in 6BR?
I see most BRs are built as single shots. Am I choosing the wrong cartridge for a repeating rifle?

How far do you want to shoot. A br isn't going to get you way out there. Defiance makes
some great actions. Kirby Allen uses (sells) them. Long Range benchrest shooters usually
remove the bolt and load from the back. It's fast and no bullet deformation or scratches.
And as I stated in another thread, Look at the 6mm Dasher.

6br is supersonic to around 1300yds.
It's a respectable target round to 1k.
It's competitive to 600yds.
It's easy to load for.
Lapua brass and ammo is readily available.
And, they're great fun to shoot for thousands of rounds.

It's everything he asked for up front.

Now if you want to anchor an Elk at 950, then you need to look elsewhere.

6XC, Dasher, BG, etc isn't going to do that either. And, if you're really trying to be competitive at 1k or beyond, then you need to look at heavier calibers.

Like your opening question/statement... how far?
The next question is... What are you shooting at?

It will mostly be used for paper and steel 300-700 yards. I will shoot it beyond that but not too often. It'll shoot some gophers and pds, probably an occasional coyote or antelope. I have a sendero 25-06 and a custom 700/Mcgowen 7 mag for hunting or reaching any further. I want something that burns a whole lot less powder than those.

I know there are several good improved vesions of the BR. I think I'll like the simplicy of the plain old br and do not want to fireform brass for this rifle. Just buy Lapua brass for less than $80/100, load and shoot, sounds good to me.

I wasn't sure Defiance made Left hand actions. I couldn't find anything on their website and assumed they didn't. I have wanted to support the local economy and put together a "made in Montana rifle". The Defiance looks sweet, I'll give them a call.

Are the Wyatts BR boxes new? I know a lot of guys use their extended box. Anyone use the BR one?

The simplicity of the 6br brass and loading is a huge plus. I just loaded 30.0 grains of Varget with Lapua brass (minimal prep) with CCI BR4 primers and topped it with a 105 Berger and started shooting .25 MOA.

My son shot a couple of weeks ago and the 100, 200, 300, 400, 500 yd drops were dead on. We haven't shot farther as yet. But, our confidence is very high.

Stiller makes bottom metal now that uses the Accuracy International magazines and there are articles on 6mmbr.com and snipershide attesting to the success that folks have had with making 6br repeaters for tactical applications using those magazines.

I may actually go that route myself in lieu of the BDL bottom that I currently with my TAC-30 and Manners T4a.
